ASEG VIC Technical Meeting Night: Advances in the geoscientific application of computer vision

Wednesday, June 16, 2021

ASEG Victoria is pleased to announce the first of our winter series of in-person branch events with another superb technical meeting night.  You are cordially invited to join us for a talk by Mr. Mark Grujic (Director, Solve Geosolutions) on Wednesday June 16th from 6pm at The Kelvin Club.  Admission to this event is free for members so please ensure you have renewed your membership for 2021 before registering.

Advances in the geoscientific application of computer vision


One of the most common datasets available to exploration geoscientists is drill core imagery. Unfortunately, the huge range in quality and general state of core photography can be an impediment to many data-driven image analysis processes. In this talk, methods of dealing with some of the shortcomings of core photo data will be introduced.  Some such methods include the application of Self-Supervised-Learning to obtain models that are agnostic to lighting conditions, blur, resolution and other unwanted artefacts, as well as digital inpainting of geological information in photos that have been masked by core-markup or other obfuscations.  The validity of these processes to gain new insights from geophysical datasets including potential field geophysics data will be discussed.


Bio: Mark graduated from Monash university with a Bachelor of Science with Honours in geophysics. He spent 8 years with Rio Tinto Exploration in Perth and Santiago, initially working on geophysical hardware and processing algorithms, then supporting global exploration programs.  Since 2018, he has worked Solve Geosolutions, Australia’s first dedicated geo-data-science consulting group. In 2019, Solve launched Datarock, a mining and exploration focused computer-vision company, where Mark provides technical insight and product development support.


Note: Light refreshments will be served during the evening.

The Future of Cloud-based Spatial Geoscience Data and its Application in Exploration

Tuesday, May 25, 2021

ASEG Victoria is pleased to announce the second of our autumn series of in-person branch events with another technical meeting night.  You are cordially invited to join us for a talk by Dr. Fabian Kohlmann (Managing Director, Lithodat Pty Ltd) on Tuesday May 25th from 6pm at The Kelvin Club.  Admission to this event is free for members only, so please ensure you have renewed your membership for 2021 before registering.



The Future of Cloud-based Spatial Geoscience Data and its Application in Exploration


Well managed, standardized data is vital for the resource industry as it currently undergoes an intense digitalization phase. As most available geoscientific datasets are usually bound by regional extends and have their own attributes and requirements, it is often challenging to merge all data into a consistent global framework which can then be used across boundaries without limits. Lithodat’s vision is to provide geoscientists with global geoscientific databases and built-in analytics to gain fast new insights about regions of interest. To achieve that goal, a team of experts extract, validate and integrate data in our unique cloud-hosted relational database.


Rather than storing data from many different projects in separate spreadsheets and folders, Lithodat’s consolidation of data opens the full potential that spatial geoscience data has to offer. Using the right tools means that spatial relationships can be analyzed on the fly, helping to solve scientific questions and industrial demands alike. For that purpose, we have developed LithoSurfer, our online platform for data viewing, analytics and extraction. LithoSurfer gives quick access to regions of interest or dive into the wealth of additional information (analytical details, lab information, literature etc.) for each datapoint. All data can be extracted in multiple formats ensuring that new techniques such as machine learning (ML) and artificial intelligence (AI) can take full advantage of Lithodat's databases.


In this talk we demonstrate the data acquisition process starting in the field using our fully integrated LithoSurfer FieldApp, the range of data types captured, and tools developed to rapidly display spatial data information on LithoSurfer. The discussion also includes examples of the potential integration of new datasets within exploration workflows, and the development of new fully-integrated tools, such as on-the-fly paleogeographic reconstructions which lead to an improved understanding of tectonic events and changes in paleo-topography through time


Bio: After three years of Equinor sponsored post-doctoral work at Bergen University, Norway, Fabian joined Neftex Petroleum Consultants in 2013 to develop global paleo-digital elevation models and build a global thermochronology database for integration into plate modeling, basin modelling and gross depositional environment mapping workflows. After Neftex became part of Halliburton, he was put in charge of the thermochronology team and became part of Halliburton’s global Source-to-Sink project. Fabian left Halliburton in 2018 to join Lithodat Pty. Ltd., a new cloud-hosted geoscience data company based in Melbourne. Fabian holds a PhD degree in Earth Sciences from the University of Melbourne and a MSc degree in Geology and Paleontology from the Ludwig-Maximillian University in Munich, Germany.


Note: Light refreshments will be served during the evening.

ASEG Victoria – Technical Meeting Night

Thursday, April 22, 2021

ASEG Victoria is pleased to announce the restart of in-person branch events starting with the first technical meeting night of 2021. You are cordially invited to join us for a talk by Mr. Warren Gray from Seisintel on Thursday April 22nd at 6pm at The Kelvin Club.  Admission to this event is free for members only, so please ensure you have renewed your membership for 2021 before registering.



The last three years have been a whirlwind for the offshore marine seismic survey industry. Through 2018-2019 Shearwater had bought WesternGeco’s fleet of 10 seismic vessels and then acquired 7 vessels from CGG. In 2018 Axxis Geo Solutions entered the Ocean Bottom Seismic market with the largest OBN survey conducted in the North Sea. Ocean Bottom Seismic companies Magseis and FairfieldNodal merged. Suriname and Guyana were the new hot spots and West Coast Africa was as busy as ever. Optimism was tentatively returning to discussion at the big exploration conferences. And then 2020 brought about the challenges of COVID-19 with plunging oil prices, slashed exploration budgets, halted projects and challenges in crew and vessel movements. A number of players entered bankruptcy protection or had their banks withdraw support of ongoing vessel operations right in the middle of projects. Using some tools from the Seisintel, we will discuss where the most recent proprietary and multiclient seismic survey activity has been, the latest technologies and acquisition methods being deployed by the industry and look forward to discussing some bright spots of the coming year.


Warren Gray completed a Bachelor of Surveying at Melbourne University in 1996. Offshore work was always of interest and after cold calling one company in Singapore and a brief ten-minute phone interview, Warren was on the plane one week later. Work was as a navigator and navigation data processor for Western Geophysical on their 3D seismic vessel M/V Western Legend. After three years and during the oil price downturn of 1999 where oil was US$12-barrel, Warren made another cold call from a ship off Angola in West Africa to Veritas (now CGG) in Singapore and was lucky to be offered another job straight away. After six years mostly on the 2D and 3D vessel Pacific Sword around the Asia-Pacific and being married during that period, onshore life was calling in order to start a family. Warren worked as a Survey Officer and later as Environmental Monitoring Manager for the Port of Melbourne during the channel deepening dredging project to deepen the shipping lanes into Melbourne. This brought about a steep learning curve into the GIS and desktop mapping world. The work in the GIS arena proved to be critical to his next role in 2009 where he was geodetic support for Fugro-Geoteam and then CGG. Tasked with design, mapping and planning of marine seismic surveys for tenders and operations, the insight into all facets of the industry were continually compounding. When the opportunity came up late in 2016, Warren jumped at the chance to work with Searcher Seismic and is now Technical Director of their Seisintel product range.

Light refreshments will be provided on the evening.  The committee looks forward to this long overdue reunion with fellow members.  We hope to see you all there once again!

Seismic surveying has been demonstrated to be the most effective technique to image sub-surface geological structure, particularly within sedimentary basins characterised by sub-horizontal stratigraphy where seismic energy is readily reflected back to the surface. However, there are some examples where seismic acquisition does not provide the most effective results: 1) where the area of interest lies along the coastal transition zone making acquisition problematic, 2) where there are sub-vertical geological structures (such as faults) which cause the seismic energy to be reflected away from the sensors and 3) where volcanic rocks attenuate the seismic signal.

Airborne Gravity Gradiometry (AGG) is a technique which measures very small changes in Earth’s acceleration. This approach is appropriate for the Otway Basin particularly in the transition zone where the geology is poorly understood. Qualitative interpretations can be made in map view, but data can also be quantitatively modelled using forward and inversion modelling processes. This approach makes airborne gravity gradiometry a complementary dataset for most of the seismic in the Otway which is dominated by 2D lines. Therefore, airborne methods provide an opportunity to not only ‘fill in the gap’ along the coast between seismic data collected off-shore and onshore, but there is also potential to add further detail to horizon geometries in between the more widely spaced (3-4km) seismic lines.

A new airborne Full Spectrum Gravity and magnetic survey has been undertaken as part of the Victorian Gas Program (VGP) using CGG’s FALCON® airborne data acquisition system. Flying commenced in August 2018 and was completed by early January 2019 (12 weeks). A total of 31042 line km of gravity, gravity gradiometry (Full Spectrum), magnetic and laser scanner data were acquired along 500 m spaced lines in a NW-SE orientation and 15000 m perpendicular tie lines. The surveyed region includes approximately 16000 km2 of the Otway Basin in Victoria, stretching from the edge of the Otway Ranges to the South Australian border, and from south of the Grampians to approximately 18 km offshore. Data were acquired at an altitude of 150 metres, increasing to 300 metres over built-up areas. A single engine Cessna Grand Caravan 208B was used to conduct the onshore portion of the survey and a DHC-6-100 (Twin Otter) aircraft was used for the offshore component. The survey has resulted in the largest airborne gravity dataset ever collected in Victoria and provides superior quality gravity imagery, compared with pre-existing data.

This presentation will visit a range of topics including the initial rationale for the survey, survey design, instrumentation and acquisition, but some emphasis will be placed on the new Full Spectrum product now being offered by CGG. This survey is the first publicly available Full Spectrum Falcon survey and is intended to capture the full spectrum of wavelengths by conforming the short wavelengths from the gravity gradiometry, with the longer wavelengths obtained from concurrently acquired conventional gravity.


Mark completed Arts/Science and Master of Science degrees at Monash University and then completed a PhD at The University of Melbourne in 2008 which involved acquisition, interpretation and modelling of an airborne geophysical survey over the Lambert Rift region in East Antarctica. Since then, Mark has worked at the Geological Survey of Victoria building regional 3D framework and rock property models using geological and geophysical datasets. Mark's time is now split between the GSV, and The University of Melbourne where he lectures in Applied Geophysics.

VIC Technical night: QGIS for Geoscience – Drill holes & more.

Wednesday, July 31, 2019


Please join us on the 31st of July at 6 pm, at the Kelvin Club.

We will have the pleasure to listen to Roland Hill from MMG Ltd who will be presenting about: QGIS for Geoscience – Drill holes & more.

Please RSVP on Eventbrite by the 30/07/2019 noon.

Any dietary requirement please email directly to


Earlier this year MMG's Group Manager for Innovation & Geophysics, Roland Hill, made a small but influential splash amongst the Geoscience community with the release of his QGIS plug-in. QGIS is an open-source, cross-platform Geographic Information System. It's small CPU footprint and low RAM requirements makes it well suited to academic and professional applications alike, while it's availability in 48 languages makes QGIS ubiquitous amongst geoscientists world-wide. In short, it's a useful, versatile piece of software which MMG, and many companies like it, use daily. And that is exactly what makes Roland's contribution so important – it’s extremely useful. His plug-in already extended the use of the standard package and with this update, Geoscience for QGIS v1.0, user functionality is extended even further to allow creation and display of drill hole sections


Roland Hill is a geophysicist with 28 years’ experience exploring for gold, copper and zinc throughout Australia, Africa, SE Asia and South America. He is currently Group Manager Innovation & Geophysics for MMG based in Melbourne. An accomplished software developer, he specialises in integration of open source libraries for geospatial processing and visualisation.
